Do I understand that in various beach resort towns such as Miramar or Mar del Plata (in the Costa Atlantica of Buenos Aires province), Punta del Este or others on the Uruguayan coast, and Balneario Camboriu (on the coast of southern Brazil), there are a number of retirees living there especially in the low season (i.e. outside summer)? If so, is it because retirees in those places want to enjoy the quiet of the low season? In the case of the south Brazil coast, is it also for the somewhat warmer temperatures than those found in the Rio de la Plata itself?
